今天突然有很多用户出现不能登录我们“问房圈”小程序的问题，经过一番排查，发现故障出在app.js中

onLaunch function中的一行代码，示例如下：

onLaunch: function (options) {

    this.globalData.options = options;

}

之前一直运行正常，今天突然发生用户不能正常使用过的情况，错误信息如下：

thirdScriptError

Cannot read property 'split' of undefined;at pages/circle/circlehome/circlehome onShareAppMessage function;at api shareAppMessage fail callback function

TypeError: Cannot read property 'split' of undefined

    at Function.fail (weapp:///pages/circle/circlehome/circlehome.js:557:37)

    at Object.fail ([publib]:5:2500)

    at Receiver._receiver.onmessage (C:\Users\PVer\AppData\Roaming\Tencent\微信web开发者工具\package.nw\node_modules\ws\lib\WebSocket.js:146:47),count=1

之后，将代码更改为：

onLaunch: function (options) {

    for(let option in options) {

        this.globalData.options[option] = options[option]

    }

}

一切正常，这是为什么？

另外，请帮忙尽快审核下我们的小程序吧，小程序名"问房圈"。
